Data synchronization method and data synchronization device

Abstract

The invention provides a data synchronization method which is used for migrating data in a source database to a target database. The data synchronization method is characterized in that the data synchronization method comprises the following steps: judging whether current time is equal to or later than a data time point and delay time or not, if so, entering a data synchronization step, and otherwise, rejudging after waisting for certain time; synchronizing the data, i.e., migrating the data of the source database to the corresponding position of the target database; meanwhile, recording the number of migrated data strips; judging whether the strip number of data synchronization is greater than the product of the current experience strip number and a preset threshold as a coefficient, if so, ending migration, and otherwise, waiting a preset waiting time duration and then returning to the step of data synchronization; meanwhile, recording the accumulated waiting duration; recalculating to determine the experience strip number and delay time according to the number of the migrated data strips in the data synchronization record; and returning to a start step.

Description

technical field [0001] The data storage technology of the present invention is specifically a data synchronization method. The invention also provides a data synchronization device. Background technique [0002] In the network management system, communication system, e-commerce, and banking system, a large amount of system data is continuously generated. If the system fails, the loss of this data can have serious repercussions. To this end, the data needs to be backed up in time. At the same time, these data may face a large number of queries at any time. In order to speed up the progress of the query, it is also necessary to store them in databases in multiple different locations. [0003] In the prior art, there are mainly the following two methods for backing up these data. [0004] 1. Manual operation Use the tools that come with the database to export the data into files, then process the files and import them into another database. This method is generally used wh...

Problems solved by technology

However, the developed tools are highly coupled with the application scenario. Due to the limitations of the content, algorithm, and cycle of moving data, the tools are difficult to reuse

[0006] For various network management and communication systems that continuously generate new data, timely data synchronization and data backup are crucial, but none of the above existing technologies can achieve reliable periodic data synchronization

The first solution requires constant manual intervention, which is not only inefficient and uneconomical, but also prone to errors

The second solution is usually highly coupled with specific application scenarios and cannot be reused in different data synchronization occasions

In particular, various parameters involved in data synchronization cannot be defined, and it is also difficult to correct errors in data synchronization
